DEVICE.

Patented Aug. '7, 1917.,

Application led September 15, 1916. Serial No. 120,265.

To all whom t may concern.'

Bc it known that we, (l) PAUL BALKo and (2) ANTON Koovsn, (1) a subject of the King of Hungary and (2) Aa citizen of the United States of America, residing kat Milwaukee, in the county of. Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Non-Skid Devices, of which the following is a specification'.

This invention relates to new and useful4 improvements in non-skid devices.

The prim ary object of the invention is the provision of a two part non-skid device adapted for ready attachment to an automobile wheel whereby the 4dirt of the roadbcd will be laterally diverted during travel.

A further object of the device is the provision of a non-skid device for wheels adapted for removable attachment to the tread portion of the rubber tires thereof and h aving suitable attaching means as well as being provided with means iny contact with the tire tread to prevent the device from creeping; thereon. f

lVith these general objects in view and others that will appear asl the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing and then claimed. Y

In the drawing forming a part of this 'application andin which like designating i being broken away. i6

characters refer to corresponding parts throughout the several views Figure 1 is a side elevation ofaV wheel provided with 4the present ,'device, portions Fig. 2 is an edge view of moved from-the Wheel.

Fig. 3 is a radial sectional view.v taken the device rei upon line H1-III of Fig. 1, andk Fig. i is a detail perspective view of anv end portion of one of the non-skid members.

Referring more in detailto the drawing, the device consisting of two substantially semi-circular non-skid sections 1() is herein illustrated in Fig, 1 operatively lmounted upon the tread portion of the pneumatic tire 11 of a wheel 12 having the usual. felly 13, rim la and spokes 15.

The sections 10 are preferably formed of metal that is light in weight andY consists of parallel sidestrips 16 having beveled edges 17 upon their inner'cr concave faces and a plurality of spaced non-skid plates 18 are.v

obliquely positioned in parallelism spanning,

the strips 16, the said plates having sharpened outer edge portions or blades 19 projecting outwardly of the strips 16 adapted for engaging' the road-,bed duringthe travel of the wheel 12 thereover-when the device is operatively assembled thereon. The inner curved faces 2O of the plateslS are corrugated as illustrated at 21 in Fig. 1.of the drawing for engaging the tread portion of the tire 1 1 adapted to prevent the sections 10 from creeping around the tire orslipping relatively thereto.

The adjacent free ends 22 of the strips 16 to the bolts 26, the said yokes passing between the spokes 15 within the rim 14: land felly 13 and securely clamped in such position by means of said bolts 28, the bolts 26 acting as hinge bolts for thecpposite adjustable portionsof the yokes.l

From this detailed description ofthe device, the mannerbf construction aswell as a wheel with the non-skid plate portions 19 at once apparent. During the travel of. the

wheel l2 over the road-bed, the sections 10 are retained. in their seated positions upon the manner of attaching the sections 10 upon 4projecting outwardly from the tire will be l the tire 11 by means of the yokes 27 and are prevented from slipping along the tire byv means of the corrugations 21 which engagingly contact the tire tread, while the oblique arrangement ofthe plates 18 throws the particles of the road-bed laterally instead of directly in! the rear of thevehicle with which the device is provided. If de-4 si'red to throw thedust` eutwardlyat vthe sides of the road, the plates 18 upon the opposite wheels of the vehicle will converge forwardly being oppositely arranged upon the opposite wheels while if it is desired to throw the dirt inwardly of the wheels the plates 18 will be arranged to converge rear- :Lesesaal validly. a separate pair of the sections l() being provided for each opposite wheel of the vehicle and the plates-18 thereof being oppositely inclined.

A non-skid device for tires, as a/unit conforming to the general peripheral outline of the tire and including essentially opposite spaced semi-circular members, each member consisting of parallel plates in Width adapted to extend inwardly along the lateral portions of the tire to a certain depth thereof and to overlie the periphery of the4 tire to a limited (attentg said parallel plates having arranged at their ends angular members with one Wing thereof seeuredlaterally to' said plates and the other wing thereof outstanding edgewise to said plates, said edgewise disposed wings of said angular members havngeonneeted thereto the outerends of the halves or sections of two-part yokes, said yokes being adapted to clamp against the inner circumference of the wheel-telly, the inner ends of said yoke-sections being bolted together.

In'testimony whereof we affix our signa tures.
